Quote from @Scott Meech: Do you the mechanics of having an MTR?

It is a mechanism towards retirement. 

This is because it was poorly converted, improperly done, "patched up" over time, and might have mixed up mechanicals etc.

Just to add ,  not every inspection covers a visual of the septic tank . if they run the water and all mechanicals, they are working fine . other than a visual there are no signs of it not working . 

Her tenant payment comes from a government entity and is $2100 per month. the house was also recently renovated so all the mechanicals are in good shape. 

If they aren't actually filed, there is no way to recoup money through the normal mechanisms. 

I often find that, when talking about future possibilities, and the mechanics of behavior and the economy, often end with with an open ended conversation.

How old are the mechanicals? 

Updated all the mechanicals, designed a brand new commercial space, and remodeled the residential apartments.

I am not opposed to realtors.That being said, the mechanics are to figure out the value of your Palace, either by learing about comps or having someone knowledgable figure comps.
